According to the myth, Extes sacrificed his son to the Voidbringers in exchange for knowledge about the day of his death.[1] He was punished by being made immortal, and then having his arms torn off every day. This tale was well-known in Alethkar, often told among the darkeyes.

His story was one of many involving men made immortal and then tortured for eternity.[1] This is potentially related to the Heralds, who were immortal and tortured in Damnation after every Desolation.[2]
